LOCKING: nnvrcn. I

Application fiIed March s, 1928. Serial No. 2 0,614.

locked into position upon a suitable supporting hook.

Another object of my inventionv is to provide a device of this character which shall be simple, cheap to construct, and which will ment on the hook will automatically lower it to its free position when the lock is open. Other objects of my invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof, it being understoodthatthe above general statement of the objects of my invention is intended to generally explain the same and not to limit it in any manner.

Fig. 1 is a perspective view. showing the improved device.

Fig. 2 is a sectional view on the line 22 of Fig. 3. V

Fig. 3 is a sectional view on the line 33 of Fig. 2. v

Fig. 4 is a side elevation of the coat hook. Fig. 5 is a perspective view of the hat hook. The device comprises the U-shaped casing 1 having lateral flanges 2, which can be suitably connected to any suitable support S. The coat hook 3 is provided with an upstand-.

ing portion 4 which is provided with a ratchet 5 whose teeth are downwardly inclined. The upstanding hook portion 4 is adapted to slide within the housing 1, being restrained from lateral movement by means of pins 6.

A lock L of any ordinary type is suitably connected to the side of the housingl, as for example, by means of rivets 7. The lock L is provided with a key actuated ratchet 8 which is clearly shown in Fig. 3. By manipulating the lock L by means of a suitable key, the lockratchet- 8 can be caused to protrude within the housing 1 so as to engage the ratchet 5 and to restrain the hook 3 from any downward movement. The housing 1 is provided with lugs 9 which are perforated to serve as 'a mount for apivot pin 10. The

pivot pin 10 is suitablysecured to the housing 1 and it serves as a support for the hat hook 11. The'hat hook 11 is provided'with an arm 12whichextends-within the housing 1. The member 4.isprovided with a longitudinal recess 14 in whiclrthe arm12 is adapted to projectso as to limit the slidingmovement of the member 4 within the housing 1. AsshownjiniFig.1, thefront of the housing 1 is cu't away to leave anopenspace above and below the lugs This limits the turning movement ofarm l2, whenthe hook 3 is moved downwardly.

.It will be noted-that the coat hook 3 is provided with a wide lateral end 3 so that the ordinary hanger of a coat cannot be slipped over the hook.

The pivot pin 10 projects through an opening 10' in the coat hook 11. The ratchet 5 is provided with a smooth head 15,'and said ratchet 5 is held in place by means of a screw 5. I r

The operation of the device is as follows:

The locked position of the parts is illustrated in Fig. 1. lVhen it is desired to hang a coat upon the hook 3, the lock is operated by means of a suitable key so as to release the ratchet 8 from the ratchet 5. The hook 3 can now be moved' downwardly and its weight will tend to make it fall to its lower position. i

The downward movement of thecoat hook 3 will cause thehat hook 11 to. turn upwardly. V

' The key can now be manipulated so as to urge the ratchet 8 into its operative position, and

the coat can now be placed upon the hook 3.

The hook 3 can now be pushed upwardly into the locking position because the ratchet 8 can yield inwardly to permit this movement. The ratchet 8 automatically locks the hook 3 in its upper and locking position. 7

To remove the coat it ismerely necessary to manipulate the lock so as to release the ratchet 8 from the ratchet 5. The weight of the coat then forces the'ho'ok 3 downwardly simul- Hence, after'a person moved his coat, it is not possible for him to p changes and omissions could be made without departing from its spirit.

I claim:

1. A locking device comprising a casing, a lower member slidably mounted in said casing, a movable latch device connected to said casing, connecting means intermediate said lower member and said latch device adapted to cause the outer operative end of said latch device to move away from said lower member, when said lower member moves downwardly, and means for locking said lower member in position.

2. A locking device comprising a casinghaving an opening in a wall thereof, a lower member having a slidable extension extending into said casing, a latch device superposed with respect to said. lower member, said latch device being pivotally mounted on said casing, and having an extension fitting within a recess of the first-mentioned extension so that the upward movement of said lower member causes said latch device to be turned downwardly, and means for locking said lower member in position.

3. A locking device comprising a casing having a front wall provided with an opening, a lower member projecting in front of said front wall, said lower member having a slidable extension extending into said casing, the side walls of said casing having lugs adjacent said opening, a latch device pivotally mounted 0 said lugs and having an extension projecting into said casing and into a recess of the first-mentioned extension so that an upward movement of said lower member causes a downward turning of said latch device, one of the lateral faces of said slidable extension having ratchet teeth, and aglocl: controlled plunger associated with one of the side walls of the casing and projecting into said casing and adapted to engage said ratchet teeth.

In testimony whereof I affix my signature.
